The incident occurred in the third period as the Devils battled the Canucks in a tie game at home. Canucks rookie Jared McCann carried the puck around behind the Devils net, and Larsson met the 19-year-old on the other side with a hit into the boards.
McCann was slow to get up but eventually made it to the Canucks' locker room. The officials deemed the play worthy of a five minute major for interference and a game misconduct, and Larsson made his way to the showers early.
If the Department of Player Safety takes a further look at this, it could result in the first supplemental discipline of Larsson's career. Luckily for the Canucks (and honestly, for Larsson) McCann returned to the bench a few moments later after passing a concussion test.
